Suggest a Crimper tool

I do a lot of my own electrical work in my house,. Also I do lots of audio cable work, so lots of soldering.
however anytime I need to crimp something, I use a pair of pliers and make do.

Now that I am working on this old Dart, with these Packard 56 terminals, the pliers is just not working. Is there a good crimper I could buy, that would be able to be used on different sizes of terminals etc...

Thanks for any suggestions.
